An official document from leading graphics designer Sapphire has been exposed by a Chiphell Forum Member which lists a bunch of Non-Reference Variants of the AMD Radeon HD7970 GPU.

The models which have been listed include the following:

Sapphire ATOMIC RX (HD7970)- (Core:1335Mhz/Memory:5735Mhz,3GB GDDR5) – 2 x Mini DP, 1x HDMI 1.4a, 1 xS Link DVI

Sapphire ATOMIC WC (HD7970)- (Core:1335Mhz/Memory:5735Mhz,3GB GDDR5) – 2 x Mini DP, 1x HDMI 1.4a, 1 xS Link DVI

Sapphire Toxic 3G (HD7970)- (Core:1125Mhz/Memory:5600Mhz,3GB GDDR5) – 2 x Mini DP, 1x HDMI 1.4a, 1 xS Link DVI

Sapphire Flex 6G (HD7970)- (Core:925Mhz/Memory:5500Mhz,6GB GDDR5) – 6 x Mini DP

Sapphire VaporX 3G (HD7970)- (Core:1010Mhz/Memory:5500Mhz,3GB GDDR5) – 2 x Mini DP, 1x HDMI 1.4a, 1 xS Link DVI

Sapphire Dual Fan 3G (HD7970)- (Core:925Mhz/Memory:5500Mhz,3GB GDDR5) – 2 x Mini DP, 1x HDMI 1.4a, 1 xS Link DVI

Sapphire Da Original 8) (HD7970)- (Core:925Mhz/Memory:5500Mhz,3GB GDDR5) – 2 x Mini DP, 1x HDMI 1.4a, 1 xS Link DVI – Reference Edition

The Atomic WC/RX Series HD7970 GPU would feature a Pre-Equipped Liquid Cooler, Monster Core Clocks (1335Mhz) and a Single Slot Design just like Sapphire’s previous Atomic Series card (HD4870x2 Atomic):

The Flex 6G would be a great card for Eyefinity/Multi-Display users gaming on Super High Resolutions where the extra 3GB memory would shine, While the Toxic and VaporX series would be great for users looking for Non-Reference HD7970′s with higher cooling capacity. Pricing and Release Date’s have not been detailed yet but the GPU’s would most probably show up soon after the official launch on 9th January 2012.
